Application filed May 26, 1911. Serial No. 629,675.

To all whom it may concern:

.Be it known that I, JoHiI PEARson, a citizen of the United States, residingat Chicago,

in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Roofs,.of which the foldescribed and then vention, "parts being omitted for the pur-- ,.p ose of illustration; Fig. 2 is a sectional View .on theline'2-2 of Fig. 4; Fig. 3 is an designates the ridge-pole,

enlarged detail View of parts at the end of Fig. 2;' F-ig. 4 is an end view ta-kenat the eaves, and Fig. 5 is a sectional view of the carlines taken at the ridge-poleon the line 5- 5'of Fig. 2.

In the drawings the reference numeral 10 .11 the side-plates, 12 the brackets bolted tothe side-plates at intervals along their length, and 13 the-longitudinal wooden purlins. Extending transversely of the car at suitable intervals are I the metal .carlines which in the present invention are U-shape in cross-section comprising horizontal webs 14 extending from side to side of the car and resting upon the side-plates and ridge-pole into which they are stepped asshown in Figs. 4 and 5 respectively, 'vertical Webs 15, and lateral flanges 16, the 'horizontal webs'being ex- "tended beyond the side-webs and side-plates the car and bent. down to form seats for the side-plates as at 17. The carlines are connected to the side-plates'll also by means of the metallic brackets-12 which are bolted" to the plates and to'the lower portions of the" bodies of the carlines as clearly shown in Fig. 2. The carlines are also stepped into the'purlins and these parts are secured. by bolts or other suitable connecting devices as clearly shown at 18 in Fi 1 and2", so that, the'carlines carry. the pur ins and the su er- ..posed roof-sheets; the carlines and -ri gepole are also bolted together as at 18. The gflanges-lfi 'of the 'carlmes are substantially subjected; the inner ends of straight from end to end so that the overall width of the c-arlines .is approximately uniform throughout their length, but the trough-portions of the carlines aremarrower at the ridge pole than at the eaves, as clearly shown in Figs. 4 and 5, the side-webs 15 being tapered longitudinally or bent gradually inwardly from each end toward the center-for this purpose. The roof sheets or panels 19 which extend from the ridge-pole" outward to the eaves rest upon the purlins 13 and each sheet or rectangular in shape upturned side flanges panel is substantially and is provided with 20, an upturned inner ,flange 21, and a downturned outer flange or end 22 adapted to extend down upon and be fastened to the outer face of the side-plates.

The carlin -caps are of metal and are of inverted trdhgh -'shape consisting of an upper horizontal portion 23 of suflicient width tooverlap adjacent flanges 20 of a pair of roofipanels or plates, downturned sides M, and 25, and they extend from the ridge-pole outwardly to the eaves where they are provided with downturned outer ends 26 overlying the downturned portions of the 'carlinesand roof-lpanels, suitable fastening bolts 27 passing t rough the downturned portions 17 and 26 and the side-plates. After the rooflaterally extending side-flanges plates are assembled upon their supporting purlins on each side of the carlines, the carline-caps are slipped into place, each along thelength of the associated carline from the caves to the ridge-pole and embracing the flanges 20 of the adjacent panels beginning at its outer end and when each cap is in position its downturned sides 24 embrace the lateral flanges of its carline and overlap-the upturned flanges'20 of the associated panels leaving the latter flanges free to move or play under. strains or twisting actions of the car. By th are interlocked with the carlines in such manner as to retain them in position but is organization the roof-plates permit them to have play or movement under any strains to which the car may he the panels have room-for play between the narrower or reduced central portions of the carlines and the downturned sides of the caps, and the outer ends between the outer ends of the carlines and the caps, all as clearly shown in Figs. 4 and 5. The outer ends 25 of the capsresting on the panels hold the latter in place, as the inturned portions of the caps lateral flanges on the upper face with subunder the lateral flanges of the carlines retain these parts in position. The carlines being stepped into'the purlins brace each purlin from the adjacent ones, and the purlins also brace each carline from the adjacent ones; and the carlines being also stepped into the ridge-pole and side-plates brace these parts.

I claim:- 1. A trough-shape metal carline having stantially straight sides, the trough-portion I being wider in cross-section at its'ends.

' on the upper face with substantially straight sides, the trough-portion being Wider in cross-section at its ends, purlins into which I the cal-lines are stepped, panels on the pur- "lins and having upturned flanges under the lateral flanges of the car-lines, and caps on the carlines having tops and sides covering the ointsbetueen adjacent panels, the sides ofthe caps being inturned under the lateral flanges of the carlines and resting at their edges on the panels at a distance from the upturned flanges thereof.

t. In a carroof, a plurality of trough- 'shape metal carlines having lateral flanges on the upper face with substantiallystraight sides, the trough-portion being Wider in cross-section at its ends, purlins secured to thehndersides of the car-lines, roof-panels having upturned flanges adjacent the car- Copies of this patent may be obtained for line-Webs, and carline-caps of inverted trough shape having tops and sides embracing the lateral flanges of the carlines and overlapping the upturned. flanges of adjacent panels.

5. In a car-roof, side-plates, a ridge-p0le, a series of purlins, a series of metallic bodycarlines extending the Width of the car above the pole and purlinsand U-shape .in cross-section with lateral flanges, means to secure the carlines to the pole andto the purlins at their intersections therewith, rec-- tangular metallic panels overlying the purlins intermediate the car-lines and having upturned edges lying adjacent the carlines. and caps on the carlines having inturned sides embracing the lateral flanges of the carlines and covering the upturned flanges of adjacent panels, and the carlines having their outer ends turned down over the sideplates. i

6. In a car-roof, side-plates, a ridgepole, a series of metallic body-carlines eX- 1 tending the width of the car and; U-shape in cross-section With lateral flanges, means to secure the carlines to the pole and sideplates, rectangular metallic panels intermediate the carlines andl'iavingupturned edges lying adjacent thecarlin'es, Caps on the car-lines having inturnedsides embracing the lateral flanges of the carlines and covering the upturned"flanges of adjacent panels, the carlines and panels. having their outer ends turned down overthe side-plates and the caps having their outer ends turned down overthe downturned ends of the carlines and panels, and means to" secure the downturned ends of the caps to the S1(l' plates.

In testimony whereof I atlix my signature in presence of tWo Witnesses.
